Cohort Study of HCC Tissue and Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Two independent cohorts composed of 216 patients with HCC were enrolled in this study (cohort 1, n = 136; cohort 2, n = 80). Paired HCC tissues and adjacent liver tissues were collected from patients who underwent liver resection at the First Affiliated Hospital of Harbin Medical University between January 2008 and August 2013. All patients provided written informed consent and this study was approved by the Research Ethics Committee of the First Affiliated Hospital of Harbin Medical University. Follow-up data were collected from patients after hepatic resection to monitor and assess the overall rate of cancer metastasis and recurrence. A normal liver cell line (L02) and several HCC cell lines (Huh7, HCCLM3, SK-Hep-1, MHCC97H, MHCC97L, SMMC7721, and HepG2) were purchased from Shanghai Cell Bank of Chinese Academy of Sciences (Shanghai, China).

We obtained 49 pairs of HCC and adjacent liver tissues from individuals that had undergone liver tumor resection at the First Affiliated Hospital of Harbin Medical University from January 2016 to January 2018. All participants were asked to sign an informed consent form. The research ethics committee of the hospital approved the study. There were 5 cell lines utilized in this study, including a normal liver cell line (L02) and four HCC cell lines (SK-Hep-1, Huh7, HCCLM3 and HepG2) that were bought from Shanghai Cell Bank of Chinese Academy of Sciences. All human HCC cell lines were grown in DMEM complete medium culture plus 10% fetal bovine serum (FBS) and 1% penicillin/streptomycin and incubated at 37 °C with 5% CO2.

Evaluation of ATIC in Liver Cancer Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Huh7, HepG2 and HCCLM3 liver cancer cells were obtained from Shanghai Cell Bank (Shanghai, China). The cell lines had recently been authenticated and tested for mycoplasma. Huh7, HepG2 and HCCLM3 cells were grown in DMEM (Invitrogen, Carlsbad, CA). All media were supplemented with 10% fetal bovine serum (Invitrogen). Jtsbio (Guangzhou, China) constructed and synthesized the siRNA and shRNA lentivirus vector specific for ATIC. The sequence of the shRNA is the same as siRNA 3:
ATIC-siRNA 1: forward, 5'-CCUGCAAUCUCUAUCCCUUTT -3'; reverse, 5'-AAGGGAUAGAGAUUGCAGGTT -3' and;
ATIC-siRNA 3: forward, 5'-GGUGUCGUCGACAAGUCAUTT -3'; reverse, 5'-AUGACUUGUCGACGACACCTT -3'.
For ATIC overexpression, the full-length ATIC cDNA was amplified by PCR and cloned into the expression vector pcDNA3.1 (Invitrogen). The empty vector was used as a control. Transfection was performed using Lipofectamine 3000 reagent (Invitrogen). Forty-eight hours after transfection, cells were harvested for further analysis.

Liver Cancer Tissue Collection and Cell Culture

Check if the same lab product or an alternative is used in the 5 most similar protocols
Eighty HCC tissues and corresponding noncancerous adjoining tissues (NATs) were harvested from HCC patients who received surgical intervention at the First Affiliated Hospital of China Medical University (Shenyang, China) between 2018 and 2019. All participants were pathologically confirmed post‐surgery, and signed an informed consent form. NATs were extracted from regions over 2 cm away from the tumor. All tissue samples were quickly flash frozen in liquid nitrogen following harvest, and before transfer to −80°C for prolonged storage. This work received ethical approval from our institution. All liver cancer cells, namely, Bel7402, Huh7, HCCLM3, SMMC7721, HepG2, and LO2, were acquired from the Shanghai Cell Bank (Shanghai, China). All cells were grown in high‐glucose Dulbecco's‐modified eagle medium (HyClone) with 10% fetal bovine serum (FBS) and 1% penicillin/streptomycin at 37°C in a 5% CO2 incubator (Thermo).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
